4" Drive Wheel versus 7" Drive Wheel (Pros and Cons)

4" considerations:

• Pro: Lower Cost

• Con: Lower belt speed (3800 feet per minute @3600 rpm) does not remove metal as quickly

• Pro: lower belt speed prevents burning while working with wood and allows for small wheel usage on single speed grinders

7" considerations:

• Pro: higher belt speed (6600 feet per minute @3600 rpm) removes metal faster and more efficiently

• Con: Must be slowed down with a variable speed drive in order to prevent damage to bearings on wheels under 1.5" diameter in a small wheel holder

• Con: Higher Cost
